Alditol
aldehyde reduced to alchohol
  Acid and alchohol derivatives are formed by oxidation of the alchohol or aldehyde groups, or the reduction of the aldehyde group. When only the alchohol is oxidized an alduronic acid is formed. When only the aldehyde is oxidized, an aldonic acid is formed. If both alchohol and aldehyde are oxidized, aldaric acid is formed. Upon reduction of the aldehyde group to alchohol, an alditol is formed.

The example molecules are L-aldotrioses. The central chiral carbon, however, may be repeated and/or reconfigured to derive further monosaccharides.


Aldonic Acid
aldehyde oxidized to acid

Aldose

Alduronic Acid
alchohol oxidized to acid
 
Aldaric Acid
